This past August I had the incredible pleasure of venturing West to participate in the 10th annual TransRockies Run. A New Englander by birth, and current South Carolina resident by choice, I am as “East Coast” as they come. Having never been to Colorado or the Rocky Mountains, I knew I was going to be in for the experience of a lifetime, albeit a potentially difficult experience. As I mentioned in a previous post, training to race at altitude while living at sea level was…interesting, to say the least. So what did I discover about running at altitude?
